摘　　要：对高贝利特水泥(HBC)的性能与其他水泥进行了对比研究,论证了高贝利特水泥具有工作性能良好,水化热低,干缩小,体积稳定性好等特点;并且其后期强度增长率高;抗硫酸盐侵蚀能力强,水泥砂胶体在3%Na2SO4溶液中养护6个月后,抗侵蚀系数仍在0.97以上。根据在深溪沟水电站大坝大体积混凝土中应用的结果看,目前混凝土未出现温度裂缝,可在水工大体积混凝土工程施工中推广应用。Analysis and comparison on features of high belite cement （HBC） and other cements show that HBC has good working performance, low hydration heat, small dry shrinkage, stable volume , high later strength increment ratio etc. In addition, the anti - corrosion ability of HBC is great and the anti - corrosion coefficient of HBC mass after 6 - month curing in solution of 3% Na2SO4 is still above0. 97. According to application condition of HBC in large volume dam concrete of Shenxigou Hydropower station, no temperature concrete crack occurred up to now and HBC can be popularized and applied in massive concrete project.
